Q
What is the function of spectrum mobility?
AA. Detect spectrum holes
BB. Gather information about available spectrum bands
CC. Vacate spectrum band
DD. Monitor spectrum band
Correct Answer:
C. C. Vacate spectrum band
Explanation:
The cognitive radio users only have temporary access to the unused spectrum in the licensed band. If the primary user demands access, the spectrum mobility function of the spectrum management framework intervenes and transfers the cognitive radio user to another vacant position.
